Ukunemba kwe-plano-concave kanye nama-concave lens aphindwe kabili
Ukuchazwa Komkhiqizo
Ilensi ye-plano-concave inendawo eyodwa eyisicaba nendawo eyodwa yangaphakathi egobile, ebangela imisebe yokukhanya ukuze idlule. Lawa ma-lens ajwayele ukusetshenziselwa ukulungisa umbono wabantu abaseduze (i-myopic), ngoba abangela ukuKhanya ukungena iso ukuhlukana ngaphambi kokuthi kufinyelele ku-lens, ngaleyo ndlela kuvume ukuthi kugxile e-retina kahle.
Amalensi we-Plano-concave nawo asetshenziswa ezinhlelweni ze-optical ezifana nezibonakude, ama-microscopes, namanye amathuluzi ahlukahlukene njengezinhloso zokwakha kanye namalensi okuqothula. Baphinde basetshenziswe ekulandisweni kwe-laser beam kanye nezinhlelo zokusebenza zokwehla.
Ama-lens aphindwe kabili ama-concave afana namalensi we-plano-concave kepha anazo zombili izindawo ezigobile ngaphakathi, okuholela ekuphambukeni imisebe yokukhanya. Zisetshenziselwa ukusabalalisa futhi zigxile ekukhanyiseni kuzinhlelo zokusebenza ezifana nezinsimbi zokubona, izinhlelo zokucabanga, nezinhlelo zokukhanyisa. Zivame ukusetshenziswa kakhulu ekulandisweni kwe-beam kanye nokwehla kwezicelo zokwehla.
I-Plano-concave ye-PROCSION ne-Double-concave lens iyizakhi ezibalulekile ezisetshenziswa kumadivayisi ahlukahlukene abonakalayo. Lawa ma-lens ayaziwa ngokunemba kwawo okuphezulu, ukunemba kanye nekhwalithi. Zisetshenziswa kuzinhlelo zokusebenza ezinjenge-microscopy, ubuchwepheshe be-laser kanye nemishini yezokwelapha. Lawa ma-lens aklanyelwe ukusiza ukuthuthukisa ukucaciswa kwesithombe, ubukhali nokugxila.
I-PRORESIONS Plavo-lens ye-Plamerision inendawo eyisicaba ngakolunye uhlangothi kanye ne-concave ebusweni ngakolunye. Lo mklamo usiza ukuphambukisa ukukhanya futhi kusetshenziselwa ukulungisa noma ukulinganisa ama-lens anempilo ezinhlelweni zokubona. Imvamisa isetshenziswa ngokuhlanganiswa namanye ama-lens amahle ohlelweni lokucabanga ukunciphisa ukuhlukunyezwa kohlelo lonke.
Ama-BiconcaVe lens, ngakolunye uhlangothi, akhuphuka ezinhlangothini zombili futhi ayaziwa nangokuthi ama-biconcave lens. Ngokuyinhloko asetshenziswa ezinhlelweni zemicabango ukukhulisa ukukhanya futhi wehlise ukuthuthukiswa kohlelo lonke. Zisetshenziswa futhi njengezincwadi ze-beam noma ama-reducers ezinhlelweni ze-optical lapho kuncishiswa khona ama-beam ama-beam.
Lawa ma-lens akhiqizwa kusetshenziswa izinto ezahlukahlukene ezifana nengilazi, ipulasitiki ne-quartz. Ama-lens we-Glass anezinhlobo ezisetshenziswa kakhulu ze-Plano-Concave ne-BI-Concave lens. Baziwa ngama-Optics aphezulu aphezulu aqinisekisa ukucacelwa kwesithombe okuhle.
Njengamanje, kunabakhiqizi abaningi abahlukahlukene abakhiqiza ukupela okunempilo ephezulu kwe-concave ne-concave ephezulu. ESuzhou Jiujon Optics, i-procision plan-concave kanye nama-concave lens aphindwe kabili enziwa ngengilazi esezingeni eliphakeme, enezindawo ezinhle kakhulu zokukhanya. Ama-lens asizakala ngokunembile ukuqinisekisa ukuthi ahlangabezana namazinga asezingeni elifanele, futhi ayatholakala ngosayizi wokuhlangabezana nezidingo zezinhlelo zokusebenza ezihlukile.
Ukunemba kwe-plano-concave nama-bi-concave lens kuyinto ebalulekile izingxenye ezisetshenziswa ezinhlelweni ezahlukahlukene, kufaka ubuchwepheshe be-microscopy, ubuchwepheshe be-laser kanye nemishini yezokwelapha. Lawa ma-lens adlala indima ebalulekile ekwenzeni ngcono ukucaciswa kwesithombe, ukucaca nokugxila futhi akhiqizwe kusetshenziswa izinto ezahlukahlukene ezinjengengilazi ne-quartz. Yaziwa ngokunemba kwayo okuphezulu, ukunemba, kanye nekhwalithi, zilungele izinhlelo zokusebenza ezidinga i-Optics Performance.
